The “effectively final” concept in the context of Lambda expressions refers to ________.

  • Variables that are static
  • Variables that are unused
  • Variables that don't change
  • Variables with final keyword
In the context of Lambda expressions, "effectively final" refers to variables that are not supposed to change after they are initially assigned a value. Lambda expressions can capture and use local variables from their surrounding scope, but these variables must be effectively final, meaning they are not modified after being captured by the lambda. This is to ensure the consistency of captured variables in the lambda's behavior.
